for Firefox 2

How does the new security model in Vista affect the various interactions our code has with the OS, specifically things like updating, installing addons, caching, bookmarking, copy and paste between apps, etc.

How, if at all, has the theme stuff changed in ways that affect our ability to read default colours using nsITheme? Are there large font or other OS theme settings that break us horribly?

Is there any way for our theming system to tell if a user is running w32/XP vs. w32/Vista?

Any changes to bookmark, history or cookie import/export with IE7 for Vista?

XPInstall and Software Update -- how do we support installation into protected areas. For example, how do we install plugins.

for Firefox 3

How can we interact with their RSS platform: low-bar, to be able to import/export/migrate, high-bar, to participate in feed read/unread status

Can we pass calendar data to their Calendar app?

Can we pass address data to their address book?

How do we install global add-ons into a protected area from a running instance of the app?

What is the replacement for GDI, that's usable from native C/C++ code?

GDI+ was deprecated, and as far as I can tell, all the Windows
Presentation Framework stuff rqeuires managed code. Specifically, is
there a layer higher than raw Direct3D that allows apps to do sane
operations with image data with and without alpha, render glyphs to
such images, etc? (An answer would be fine, but if you guys could get
me an email address of someone to talk to, that would be even better. - Vlad)
